Insights
Enhanced external counterpulsation (EECP) offers long-term benefits for chronic coronary disease angina. This mechanical therapy may stimulate angiogenesis via shear stress, promoting new blood vessel growth in the heart.
Area of Science:
- Cardiology
- Biomedical Engineering
- Vascular Biology
Background:
- Decades of research suggest enhanced external counterpulsation (EECP) benefits patients with chronic coronary disease and angina.
- Previous non-sham controlled trials are now supported by a multicenter, randomized trial, strengthening evidence for EECP efficacy.
Purpose of the Study:
- To explore the long-term benefits of enhanced external counterpulsation (EECP) in patients suffering from angina due to chronic coronary disease.
- To investigate the potential mechanisms underlying EECP's therapeutic effects on myocardial cellular processes.
Main Methods:
- Review of numerous non-sham controlled trials and a recent multicenter, randomized trial.
- Analysis of scientific investigations into the effects of shear stress induced by EECP.
Main Results:
- EECP demonstrates long-term benefits for angina in chronic coronary disease patients.
- Proposed mechanism involves shear stress from EECP stimulating growth factors and angiogenesis in coronary beds.
Conclusions:
- EECP is a valuable therapeutic option for chronic coronary disease.
- Ongoing trials and registries will further clarify EECP's role, particularly in patients with left ventricular dysfunction.
Abstract:
Studies over the past several decades support the hypothesis that enhanced external counterpulsation (EECP) can provide long-term benefits in patients with angina secondary to chronic coronary disease. Numerous non-sham controlled trials have recently been substantiated by a multicenter, randomized trial. Although the mechanism by which this mechanical treatment effects an alteration in cellular processes within the myocardium remains unclear, recent scientific investigations suggest that shear stress induced by chronic exposure to EECP might result in the release of a variety of growth factors and the subsequent stimulation of angiogenesis in the coronary beds. Ongoing clinical trials in patients with significant left ventricular dysfunction, an international registry, and additional clinical trials may help to elucidate further the role of this novel and unique therapy in our clinical armamentarium.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
